SLICE MICRO has builtin connectors; SLICE NANO has wires with connectors. 31 mm 26 mm SLICE NANO 2.2. 42 mm 42 mm SLICE MICRO SLICE Modular Concept Modular system – Plug multiple SLICEs onto Base SLICE to make a Stack Each SLICE “Stack” can accommodate 8 sensor input SLICES. Each Bridge SLICE has 3 analog input channels. You may want multiple “Stacks” if more channels are needed or placement in different locations makes sense for your application. Each SLICE “Stack” consists of 1 Base SLICE and up to 8 additional sensor input SLICEs. Version 1.0f – 29 November 2012 6 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] SLICE NANO Stack SLICE MICRO Stack SLICE BRIDGE modules Up to (8) per “Stack” SLICE BASE module (1) per “Stack” Example SLICE set-up with multiple Stacks: SLICE Stacks are mounted to the device under test and chained together. The End-of-Chain Terminal can be connected to a trigger, battery, or other devices. The beginning of the chain is connected to the SLICE Interface Device, SLICE Ethernet Interface, SLICE USB Interface or directly to the PC. PC can be disconnected after arming for standalone operation. Up to 4 SLICE Stacks can be in any one chain. SLICE Distributor (not shown) allows for up to 4 SLICE chains for hundreds of channel in one set-up. Many options: • Battery • Trigger input • Monitor status • Up to 4 Stacks PC provides USB control SLICE Interface Device Device Under Test Example: Crash dummy, aircraft wing, vehicle chassis, industrial machinery, bridge structure, etc. Version 1.0f – 29 November 2012 7 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 2.3. [email protected] SLICE Basic Hardware Components Below are the basic components of a SLICE system. You will have some subset of these depending on your application or what was ordered. The table below provides an overview of the types of SLICE modules available. Some modules are only available in the MICRO or NANO version. SLICE Module Description MICRO NANO Base SLICE One needed for each SLICE Stack Yes Yes Bridge SLICE 3 channels of piezo-resistive and voltage sensor inputs. Yes Yes IEPE SLICE 3 channels of piezo-electric sensor inputs Yes No Accel SLICE Bridge SLICE with integrated 3-axis accelerometer Yes No ARS SLICE Bridge SLICE with integrated 3-axis Angular Rate Sensor Yes No Stack Battery 2-cell LiPo battery connected to bottom of Base SLICE No Yes 2.3.1. Base SLICE See Appendix A for detailed specifications. See Appendix K for information on how to update firmware. You must have at least one Base SLICE for any SLICE system. The Base SLICE is at the bottom of the SLICE Stack and has these components: Microprocessor 7 GB flash data memory standard (6.48 GB available for data storage) USB hub Power conditioning Control signals A Base SLICE MICRO is shown below. Connector to Bridge SLICE or other SLICE input module SLICE Bus Up to PC SLICE Bus Down to next Base SLICE Version 1.0f – 29 November 2012 8 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] # of Channels* Maximum Sampling Rate at Maximum Recording Time [9,000 sec (2.5 hours)] 3 120,000 samples per second (sps) 6 60,000 sps 9 40,000 sps 12 30,000 sps 15 24,000 sps 18 20,000 sps 21 17,000 sps 24 15,000 sps * All channels are recorded even if they are not programmed. How to Calculate Maximum Storage Times With 6.48 GB available for data storage, there are a total of 3.24 G samples available in each Base SLICE (each 16-bit data sample requires two (2) bytes). To determine the maximum recording time, divide the number of samples by the product of the sampling rate and the number of available channels in the Stack. 3,240,000,000 = # of seconds Sampling rate (sps) X # of channels in Stack Example 1: 10,000 sps using a 9-channel SLICE Stack 3,240,000,000 = 36,000 sec (10 hours) 10,000 X 9 Example 2: 1,000 sps using a 6-channel SLICE Stack 3,240,000,000 = 540,000 sec (150 hours) 1,000 X 6 Since the recording capacity of a SLICE system is very large, try to limit sampling rates and durations to the minimum necessary to avoid large and cumbersome data files. Large files take longer to download and may also be time-consuming to post-process or difficult to share with colleagues. Use of the Region of Interest (ROI) download can save a great deal of time if implemented properly. Version 1.0f – 29 November 2012 9 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 2.3.2.

Mounting and Connecting SLICE Hardware This section gives details on how to connect your SLICE hardware. Choose the connection method you have from the options below for the quickest information. 3.1. General Connection Guidelines Great care should always be taken when connecting any power, switch, sensor or any other device to the SLICE system. 3.2. DO NOT exceed the rated voltage input range for the device. Whenever possible use the power supply or battery pack supplied with your SLICE system. DO NOT connect directly to vehicle power or other noisy power sources. ALWAYS disconnect the battery from the SLICE system before connecting to a battery charger. ALWAYS use SLICE NANO with a heat sink as the SLICE NANO case is very thin aluminum with very little heat sinking ability. Never use SLICE NANO mounted to a thermally non-conductive surface like wood or plastic. Refer to proper grounding procedures described in Appendix G. Check that all cables show no signs of physical damage. Be sure all sensors have their cable shields ungrounded at the sensor end and grounded at the SLICE input connector. (SLICE DAS units have grounded enclosures. Sensors should be floating.) Guidelines for High Shock and Vibration Testing SLICE MICRO and SLICE NANO components can generally be used in test environments with maximum acceleration levels as high as 500 g. If you have purchased a Version 1.0f – 29 November 2012 17 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] specialized high g SLICE NANO system, it can be used in environments up to 5,000 g if proper care is taken. Please contact DTS if you have any questions about using SLICE in high g environments. Proper mounting of the SLICE system, cables, and accessories is critical to successful testing. 3.3. DO NOT mount SLICE components in an area where they may be directly impacted by an object. Use damping material whenever possible to help protect the SLICE system from excessive shock or vibration, but remember that SLICE NANO requires a heat sink. Be sure that connectors and wiring are properly secured. SLICE Connectors and Cables 3.3.1. SLICE Connectors SLICE is an ultra small data acquisition system. One challenge with a small system is electrical connections. Although connectors such as Bendix, Amphenol, and LEMO are common for instrumentation, all of these are much too large to be practical for SLICE. The SLICE system uses circular plastic connectors manufactured by Omnetics Corporation (www.omnetics.com). These connectors use high-quality, machined contacts and are used in many military, aerospace and other high shock applications. Connectors are available direct from Omnetics or can be purchased from DTS. Below are the connector types used by SLICE. See Appendix A for complete DTS part number information. Version 1.0f – 29 November 2012 18 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 3.3.2. [email protected] SLICE Cables DTS provides a number of different SLICE cable options depending on the connection needs. SLICE Stack-to-Stack connection cables are shown below. SLICE MICRO Base units can be connected together via a daisy-chain cable. SLICE NANO Base units can be connected to each other directly or via a daisychain extension cable. Version 1.0f – 29 November 2012 19 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] 13000-3005x: SLICE MICRO Chain Cable 13000-3006x: SLICE NANO Chain Cable Connections less than 8 inches Connections from ≥8 inches to ≤2 m A longer, more robust version of the SLICE NANO Chain Cable is available for connections from >2 m to ≤5 m (DTS P/N 13000-3007x). (Note: the rated maximum separation between Stacks is 5 m.) Version 1.0f – 29 November 2012 20 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 3.4. [email protected] Power Requirements The SLICE system runs on DC power. Acceptable input power can range from 9 V minimum to 15 or 20 V maximum, depending on the accessories used with your system. Do not exceed the maximum input power for the accessory you are using. To calculate the rough power needs for a particular system, use the information below: POWE R RE QUIREMENTS 10 V POWER INPUT /5 V SENSOR EX CITATION IDLE RECORDING BASE SLICE 40 mA 110 mA BRIDGE SLICE 2 mA 55 mA SENSOR LOAD (350 o hm/5 V SENS OR EX CITATION ) 0 mA 50 mA SINGLE STACK POWER C ONSUMPTION AT 5 V SENS OR EXCITATION TOTAL BASE (QTY) 1 BRIDGE (QTY) 2 SENSOR LOAD (% of 350 ohm) 100 IDLE C URRENT 44 mA IDLE P OWER 330 mW RECORD CURRENT 320 mA RECORD POWER 2400 mW Version 1.0f – 29 November 2012 21 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 3.5. [email protected] Using the End-of-Chain (EOC) Terminal A diagram showing connections using the EOC Terminal is shown below. Notes: Although this shows a SLICE MICRO system, connections with a SLICE NANO are similar. The EOC Terminal is a shock rated item. Voltage input can be provided via the included power supply, a battery or any voltage source between 9 and 15 VDC. Warning: Do not exceed the 15 VDC input voltage range as damage may result. The ON terminal must be connected to the GND on the EOC Terminal for the SLICE unit to turn on. If you connect an LED between the STS and GND terminals, you will get a Status light when the system is armed. Version 1.0f – 29 November 2012 22 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] To DN port on the last Base SLICE MICRO or NANO in a SLICE chain See Appendix B for detailed information on the SLICE End-of-Chain Terminal. 3.6. Using the SLICE System Interface The SLICE System Interface is similar to the EOC Terminal except it is used between the first/only SLICE Stack and the PC. See the example diagram below. Version 1.0f – 29 November 2012 23 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] Notes: Although this shows a SLICE MICRO, connections with a SLICE NANO are similar. The SLICE System Interface is a shock rated item. The AUX Terminal can be used for easy connection to a battery, start record, trigger, and status signal. Voltage input through the SLICE System Interface can be provided via the included power supply a battery, or any voltage source between 9 and 20 VDC. Warning: Do not exceed the 20 VDC input voltage range as damage may result. The SLICE System Interface has a recessed ON switch. Alternately the ON signal can be connected to the GND on the EOC Terminal. If you connect an LED between the STS and GND terminals on the EOC Terminal you will get a Status light when the system is armed. 3.7. Using the SLICE USB Interface The SLICE USB Interface is similar to the SLICE System Interface. The main difference is that the SLICE USB Interface is designed for bench-top, non-rugged use. See the example diagram below. Version 1.0f – 29 November 2012 24 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] Notes: Although this shows a SLICE MICRO, connections with a SLICE NANO are similar. The SLICE USB Interface is NOT a shock rated item. Voltage input can be with the included power supply a battery, or any voltage source between 9 and 15 VDC. Warning: Do not exceed the 15 VDC input voltage range as damage may result. The AUX connector is a standard D-sub HD15. This can be used to hardwire a Start Record or Event switch or monitor the Status line. 3.8. Using the SLICE Ethernet Interface The SLICE Ethernet Interface is similar to the SLICE USB Interface. The main difference is that the SLICE Ethernet Interface has an Ethernet connection to the PC instead of a USB connection. This allows for a longer communications cable between the PC and the SLICE system. The SLICE Ethernet Interface can also connect 2 SLICE chains for large system configurations. See the example diagram below. Notes: Although this shows a SLICE MICRO, connections with a SLICE NANO are similar. Version 1.0f – 29 November 2012 25 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 3.9. [email protected] The SLICE Ethernet Interface is NOT a shock rated item. Voltage input can be with the included power supply a battery, or any voltage source between 9 and 15 VDC. Warning: Do not exceed the 15 VDC input voltage range as damage may result. The AUX connector is a standard D-sub HD15. This can be used to hardwire a Start Record or Event switch or monitor the Status line. Using the SLICE Distributor The SLICE Distributor allows for the connection of up to 4 SLICE chains and converts the communications signals from USB to Ethernet. This allows for a longer communications cable between the PC and the SLICE system. The most common application for the SLICE Distributor is for an embedded system with a high channel count as shown for the in-dummy (manikin) configuration below.

Sensor ID and Supported Sensor Types This section covers basic information regarding SLICE compatible sensors and sensor ID. More detailed information regarding sensor connections can be found in Appendix H. The diagram below shows a common 4-wire bridge sensor connection to a Bridge SLICE input channel. 4.1. Sensor ID Sensor ID is also referred to as electronic ID (EID). The function of EID is for the SLICE hardware to automatically read and determine what sensor is attached to each sensor input channel. SLICE uses EID chips from Maxim IC, model DS2401 (see http://www.maximic.com/quick_view2.cfm/qv_pk/2903). To make soldering of the EID easier, DTS provides EID microcards, which have a chip scale packaged DS2401 soldered to a circuit board with wires attached (see below). Version 1.0f – 29 November 2012 27 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] EID “microcard” soldered to pins 4 and 6 Omnetics 7-pin Sensor Connector 4.2. Supported Sensor Types The Bridge SLICE supplies 5 VDC excitation up to 20 mA and supports many types of accelerometers, load cells, pressure sensors and other sensor types. The following general sensor types are supported: Full (4-wire) or half bridge (2- or 3-wire) resistive and piezo-resistive types Voltage input: Input range 0.1 to 4.9 V; larger range with voltage expander circuit Conditioned sensors with 5 V excitation and 2.5 V centered signal output Common piezo-electric sensor types If you have questions regarding what sensors are supported, please contact [email protected] and provide the sensor manufacturer and model number if available. 5. Software This section covers software installation and use. See Appendices I, J and K for additional information regarding file formats and how to update the Base SLICE firmware. 5.1. Basic Requirements SLICEWare is a Windows® based program. Minimum PC specifications are: 5.2. Windows XP, Windows Vista, or Windows 7. 32- and 64-bit versions are available. 1 GHz or faster processor 2 GB RAM minimum. More RAM is important for longer/higher sample rate data acquisition. 100 MB disk space for Software plus storage for test data 1024 x 768 minimum screen resolution Data Collection Concepts This section discusses the basics of data collection with SLICE. Version 1.0f – 29 November 2012 28 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual 5.2.1. [email protected] Standalone Operation SLICE is a standalone data logger. This means that once it is armed, the PC can be disconnected if desired. After receiving a Start Record or Trigger signal, the SLICE autonomously collects data, storing it to flash memory with no user interaction. After the test, the user can reconnect the PC to download the data. There is also a real-time mode in the SLICEWare software application that allows the user to check channel inputs on an oscillograph-looking screen. (This data can be logged.) 5.2.2. Data Collection Modes SLICE supports four data collection modes: Circular Buffer, Recorder, Hybrid Recorder, and Continuous Recorder. (Note: SLICEWare cannot simultaneously display the data while the system is recording.) 5.2.2.1. Circular Buffer Mode In circular buffer mode, the user can program SLICE to record pre-trigger data. For example, the test set-up can specify to record x seconds pretrigger and x seconds post trigger. Time Zero (T=0) is marked when the trigger signal is received. 5.2.2.2. Recorder Mode Recorder mode starts when a Start Record signal is received and continues for the time specified in the test set-up. If a trigger signal is received sometime after the Start Record, this marks the T=0 point. 5.2.2.3. Hybrid Recorder Mode Hybrid Recorder mode starts when a Start Record signal is received and continues until the unit receives a trigger signal and then records for the post-trigger time specified by the host software. The trigger signal marks the T=0 point and all data recorded is available for download. 5.2.2.4. Continuous Recorder Mode Continuous Recorder mode starts when a Start Record signal is received and continues until the Start Record signal is released. The unit will then re-arm for another event. The LEDs on the unit will flash blue slowly then rapidly, and then the STATUS LED will become solid blue, indicating the unit is fully armed. The unit will continue to record new events until it records the number of events specified by the host software. If a trigger signal is received after the unit has re-armed the unit will disarm and no longer attempt to re-arm. 5.2.3. Multiple-Event Modes All SLICE data collection modes have an equivalent multi-event arming mode. A unit armed in a multiple-event mode will re-arm when an event completes. The Version 1.0f – 29 November 2012 29 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] unit will stop re-arming when the number of events specified by the host software has been recorded. 5.2.4. Auto-Arm Data Collection SLICE can be placed in an auto-arm mode that will cause the unit to arm automatically when the power cycled. The unit can be placed into this mode and record with any data collection mode. NOTE: An event or trigger signal applied anywhere in the SLICE chain is distributed throughout the system. This applies to level trigger as well. 5.3. SLICEWare This section discusses the basics of SLICE data collection using the SLICEWare application. The SLICEWare software application allows for easy: Test set-up Sensor database management Real-time sensor check-out Test execution Data download and viewing Data export 5.3.1.

Delete: Deletes the sensor that is highlighted in the sensor list. Undo Edit: Reverts all edits made in the sensor details fields. Read ID: Reads the EID from the channel selected in the Connected Sensor list. The returned ID value will be populated in the Sensor ID field for the sensor that is highlighted in the sensor list. Measure Bridge: Measures a sensors bridge resistance from the channel selected in the Connected Sensor list. The returned bridge resistance will be populated in the Bridge resistance (ohms) field for the sensor that is highlighted in the sensor list. Save: Saves edits made in the Sensor Detail area. Manual Sensor Assignment For sensors connectors without an EID. You cannot un-assign or overwrite an auto-assigned channel. Assign: After highlighting a sensor in the Sensor List and highlighting an un-assigned channel in the Connected Sensors area, use this to assign the sensor. Un-assign: Remove the highlighted channel in the Connected Sensors area. Apply: Commits the sensor set-up information to SLICE. Note: A sensor that is manually applied should not have a value in the Sensor ID field and the SLICE should not have an EID installed on the connector. If the Sensor ID field is populated or an EID exists on the channel, the sensor will need to be re-applied after switching away from and then back to the Prepare tab. Version 1.0f – 29 November 2012 34 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] Sensor ID Refresh: The sensor IDs are read when the software is started or when a SLICE is rebooted. If sensor connections are switched, choosing refresh will read the connected IDs on the current channels.

You cannot enter directly into this field. Options Invert: When checked, the data will be inverted. Shunt Check and Bridge Resistance: When Shunt Check is checked, the sensor will have the bridge resistance measured during diagnostics and compared to the value entered in Bridge resistance. SW Filter: Choose the frequency of a software filter to be applied to the data when viewing. This only affects the viewed data as all data stored will be as collected with the hardware anti-alias filter. Zero Method (post download software zeroing): o Use Pre-Cal Zero: The Zero Measured Output (ZMO) of the sensor during calibration will be used to set the EU zero of the downloaded data. o Average Over Time: Used in conjunction with ZeroStart and ZeroEnd, the average EU value during the Start and End window will be used to Zero the collected data. The Zero Start/End window must be set to data that will be collected. If using a negative time, then the Acquire tab must include this window. o None: The actual recorded input will not be adjusted or compensated for zero level. This setting can be used to show the actual mV offset. An example may be to record a logic level signal and see the actual on/off state. o Remove Offset (hardware): When checked, this will remove the ZMO during diagnostics. This will “electrically” zero the input. o ZeroStart/End: See Zero MethodAverage Over Time. o Offset Check: Used in conjunction with Limit Low/High during diagnostics. When checked, the ZMO is measured and compared the Low/High limits as a pass/fail criteria during diagnostics. Step-by-Step Procedure to Add a New Sensor 1.

DTS SLICE systems contain protection f EMI/RFI/ESD for EMI/RFI/ESD, h however, many d dynamic i ttesting ti environments i t (pyrotechnics, blast) are particularly noisy and require the utmost attention to grounding and shielding practices. The following recommendations are intended to maximize protection and keep systems functioning properly in the harshest environments environments. Ground all DAS equipment, power supplies and sensor mounting fixtures whenever possible. This is an extremely important step toward ensuring the best performance from your SLICE system. • Always connect a cable from a good Earth ground to the test article, test fixture or instrumented vehicle. Not only does this help divert potentially disruptive electrical energy, it is also good safety practice. For remote testing applications, a metal ground rod driven 3 ft into the soil can be an effective Earthing device. • Ground G o nd all SLICE enclos enclosures es to the test a article ticle o or vehicle ehicle • • Install ground cables between all SLICE Stacks and the test article or vehicle. Install ground cables between electrically isolated test article/sensor mounting surfaces and the SLICE Stacks. © 2009-2010 DTS Principles of Dynamic Data Acquisition SLICE Grounding and Shielding Overview Shield sensor cables • • • Use shielded sensor cables. The shield provides a path for EMI/RFI energy to flow to the DAS ground and enclosure, thus reducing effects on sensor signals. Connect the sensor cable shield on the DAS side only to the “Shield” Shield or ground pin on the SLICE. Do not connect the shield at both ends. Connecting the sensor cable shield at both ends will cause large ground-loop currents that can increase noise or cause damage. • PC Grounding? g • • • This is more important than you might think. If the Laptop used to communicate with SLICE is powered from a source that has a significantly different ground potential than the SLICE system, communication with the SLICE can be impaired. In severe cases damage to the laptop or SLICE can occur. Either run the laptop p p on batteryy power p or use a voltmeter to make sure the AC outlet ground is not at a significantly different potential than the ground connected to the test article or vehicle. • Carefully consider routing and cable design for any high current signals to air bags, cameras, lights, etc. • • Route these cables away from sensor wiring wiring. Cross sensor wiring at 90° angles if the cables must cross. © 2009-2010 DTS Principles of Dynamic Data Acquisition Recommended Grounding Architecture Vehicle Body or Test Article Shield NOT connected here Sensor Cable Sensor Isolated metal structure such as a dummy component DAS Mounting Plate SLICE Stack Ground Cable Ground Cable to “Earth” Earth © 2009-2010 DTS Principles of Dynamic Data Acquisition Cable Installation Recommendations • Flat braided ground cable has lower impedance than typical round wires and hence makes a better ground connection. • Never assume that connections are good until you check them with an ohmmeter. Should be <1Ω for short runs or <5Ω for long runs. • Ground cables inside test dummies should be braided type with a 12gage equivalent size. • Ground cables from a test article or vehicle to the SLICE Stack should be braided strap type with a 15-gage equivalent size. • The cable from a test article or vehicle to the Earth connection should be large enough to create an a low impedance connection given the distance between Earth connection and test vehicle. 8 to 12 g gage g equivalent q is common. • If braided cable is not available, any ground wire is better than none! © 2009-2010 DTS Principles of Dynamic Data Acquisition Braided Cable • Alpha wire company makes suitable flat braided ground cable in 100 ft lengths.

This will be fewer than the number of samples Integer originally requested by the user if the data has been subsampled or if only a portion of the data was downloaded. Version 1.0f – 29 November 2012 81 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] Data Type Name Description UnsubsampledNumberOfSamples Integer The total number of samples collected during data acquisition PostTriggerSeconds Double The number of seconds of recorded data that the user requested after t=0 PreTriggerSeconds Double The number of seconds of recorded data that the user requested before t=0 RecordingMode String Either the value RecorderMode or CircularBuffer. Other values will be added in the future. SampleRateHz Integer The rate at which sampling occurred during data collection StartRecordSampleNumber The sample number at which the start signal was Integer first detected. The value will always be 0 when RecordingMode=CircularBuffer. NumberOfChannels Integer InlineSerializedData Boolean The number of user configured channels within the module <TriggerSampleNumbers> This is a list (possibly 0 length) of trigger sample numbers. In the circular buffer case, there will be one trigger sample number. In recorder mode, the trigger is optional. In the case of multiple event mode, there may be more than one trigger sample number. <Channels> The Channels tag contains a list of channel elements. It should have the same number of entries as NumberOfChannels in the Module tag. The type of the child elements will depend on the type of signal conditioning SLICE used. <AnalogInputChanel> The AnalogInputChanel tag corresponds to a Bridge SLICE channel. (Note: There is a typo in the tag name and “Chanel” is misspelled. It has been retained for backward compatibility.) Many of the attributes indicate how the channel was configured during the test. The AnalogInputChanel element has the following properties: Name Data Type Description ChannelType String This identifies the representation of the data contained in the .BIN file. Currently this value is always expected to be DTS.Serialization.Test+Module+AnalogInputChannel. Number Integer The channel number within the signal conditioning unit. In a Bridge SLICE, channels are numbered 0–2. Version 1.0f – 29 November 2012 82 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual Name [email protected] Data Type Description Start Date Currently unused Bridge String Either FullBridge or HalfBridge BridgeResistanceOhms Integer The specified bridge resistance used during the shunt check ChannelDescriptionString String The user provided description for the channel Description String The user provided description for the sensor; currently the same as ChannelDescriptionString DesiredRange Integer The user requested full scale Sensitivity Double The sensitivity of the sensor in either mv/V/EU or mv/EU depending on ProportionalToExcitation SoftwareFilter String The requested filtering to apply to this channel. Stored data is unfiltered, and this value must be used to apply proper filtering. Typical values are "1650hz" for CFC1000. ProportionalToExcitation Boolean Indicates if the output of this sensor is proportional to excitation. Used in conjunction with Sensitivity. IsInverted (Optional) Indicates if the data should be inverted Boolean before presenting to the user. If missing, this attribute is considered 'false'. IsSubsampled (Optional) Indicates if the data stored on disk is at a Boolean lower sample rate than the original data collection. If missing, this attribute is considered 'false'. Eu String The user provided Engineering Units (EU) (e.g., mm, g, or msec2) SerialNumber String The serial number of the sensor used with this channel CalSignalEnabled Boolean Applies to IEPE SLICE only. ShuntEnabled Boolean For Bridge SLICE only. Indicates if the user requested the channel be shunted during diagnostics. RemoveOffset Boolean Indicates if the user requested hardware offset compensation be used during diagnostics ZeroMethod String Identifies the type of software offset compensation that should be used. If the value is "UsePreCalZero," then the Pre Calibration zero value stored in the channel file should be used. If the value is "AverageOverTime," then an average value computed from the channel data should be used. ZeroAverageWindowBegin Double If ZeroMethod=AverageOverTime, this is the beginning of the window to be used for computing the average ZeroAverageWindowEnd Double If ZeroMethod=AverageOverTime, this is the end of the window to be used for computing the average Version 1.0f – 29 November 2012 83 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual Name InitialEu [email protected] Data Type Description A value provided by the user that should be subtracted Double from all scaled data in addition to the selected ZeroMethod UnsubsampledSampleRateHz Integer The sampling rate used during data collection. Valid only if IsSubsampled=true. MeasuredShuntDeflectionMv Double (Optional) If a shunt test was performed, the actual deflection of the shunt TargetShuntDeflectionMv Double (Optional) If a shunt test was performed, the expected shunt deflection MeasuredExcitationVoltage (Optional) The measured excitation voltage, if available. Used by SLICEWare for scaling proportional-toDouble excitation sensor data if "factory" excitation voltage is not available. FactoryExcitationVoltage (Optional) The factory excitation voltage, if available. Double Used by SLICEWare for scaling proportional-toexcitation sensor data.

The byte numbers are along the left side of the viewer. Boxed in white is first the DATA start offset and it can be seen that starting at the byte specified in this offset is the actual sample data. Note that it is prefaced by trailing "00" from the previous value and from then on, all sample data is consistently non-zero. Version 1.0f – 29 November 2012 86 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] Additional Info Note that the file is 'little-endian'—that is the values are serialized into the file LSB first. This is not important but should be considered if changes are to be made to the serialization procedure. It must only be consistent between read and write operations. The .NET serialization utilities Version 1.0f – 29 November 2012 87 ©DTS, Inc. - All Rights Reserved SLICE User’s Manual [email protected] currently used in SLICEWare have defaulted to this because the x86 processor architecture is 'little-endian'. Take the data offset for example. The 8 bytes read E2 00 00 00 00 00 00 00, but this does not mean the data starts at byte #1.62850163 × 10e19. E2 is the LSB, so the offset is 00 00 00 00 00 00 00 E2, or byte #226d.
